Local astronomers said that Venus and Jupiter had appeared side by side in the evening sky over the past week or so, but Monday night would be the best night to see the "face" appear.

Viewers in Western Australia have the best view, with the moon appearing closer to the "eyes" formed by the planets.

While the planets and moon appear to be close together, in reality they're not. The moon is 250,000 miles away, while Venus is 93 million miles away and Jupiter 540 million miles away.

Stargazers in Europe and Africa will miss out completely. By the time the sun sets for them the moon will appear between the planets, pushing the "mouth" between the "eyes" to create more of a Picasso-esque effect.
